This invention relates to an improved bearing structure and it has more particular reference to a contribution to this art, which is distinguished by two principal parts; namely, an improved sectional and adjustable bearing for a shaft, an' independently adjustable housing or casing therefor.

My principal aim is to generally improve upon prior patented and marketed bearings of the type embodying rollers or balls, by providing a novel organization of parts which, it is believed, is a mechanical achieve Inent in the art, and Which is characterized by such indispensable features as efficiency, in

performance, strength and durability, econ-- omy, positive and dependable results, and which is capable of fulfilling the requirements of an invention of this class in an un usually satisfactory and suitable manner.

That part of the invention hereinafter mentioned as the bearing per 'se is individualized by a novel inner race, embodying a split bushing embracingthe shaft and a surrounding annulus having adjustable cooperation therewith to provide for conformity and accurate adjustment from time to time to com:

pensate for wear and .to facilitatelinitial as sembly and subsequent repairs. I

The housing is made more practicable and modern in design in that it is associated with a supporting base throughlthe medium of a universal joint permitting adjustment and maintenance of the'housing with respect to the base in a manner to render theshaft substantially self-aligning.

Other features and advantages of the invention will become more readily apparent from the following description and drawings.

In the drawings:

.Figure 6 isan elevational view of the es.- pecially designed resilient split bushing. Figure 7 is an edge or end elevational view of the bushing. j Figure 8 is a sectional View, taken approximately upon theplane of the line 8-8 of In the drawings, vwherein like numerals I are employed to designate like'pa'rts throughout the same, the reference numerals 9 designate generally the housing orcasing, in which the lmproved sectlonal' bearing-"l0 is confine'd, and 11 designates the shaft journaled for rotation in the bearing and housing.

The housing comprises a hollow box like casing including a stationary body 12, and a removable cap 13, fastened to the body through the medium of retaining bolts 14 r and removable to permit access to be had to the interior of the housing. These parts 12 v and 13 are formed with aligned openings for passage of the shaft 11, and packing r1ngs,15 are arranged in grooves surround- The body 12 is provided 'at its bottomwith 'j an integral extension. 16,} functioning-as a restand provided with a convex or part-. spherical surface, designed for universal joint reception in a concavity formed in the base 17 As shown in Figure 4, the body 12 is provided with substantially diametrically opposite outstanding lugs 18.disposed above bolt holes in the base, and connecting bolts 19 are provided for efi'ectinga connection between the housing and base, such as permits freedom of movement of the universal joints to permit self aligningof the shaft 11. In the representation in Figured, the headed endsof the boltare located in recesses, while the screw threaded end portions extend through bolt holes in the lugs 18. The belt holes in both thefaceand in the lug are,

enlarged as at 20 to permit angling of the;

bolts and relative movement of the housing with respect to the base to produce the desired self-aligning feature of'the invention; Analyzing now theimproved bearinglO, attention is invited to theassf'embly seen in igure 3. It comprises an outer ,race 21,. clamped betweenthe body 12 and the cap13,

by the aforesaid bolts 14:. This bearing is of the usual construction. The inner race, how

ever, is distinctive, in that it includes an especially designed bushing 22, and a complemental surrounding annulus 23. l The bushing 22,as shown 1n Figures 6 to 8 inclusive 1s provided with two pairs of slots, 24 and 25,

respectively. The slots QQ-open through one edge of the bushing, while the slots 25 open silient bushing is had. The outer periphery is provided with relatively wide and narrow bevelled surfaces 26 and 27 respectively. The

p inner peripheral surface of the annulus 23 has arelatively wide bevelledsurface which corresponds to and cooperates with thesurface 26 of the bushing Moreover, it is formed with an outstanding circumferential 'liange28, assuming an angular inclination, corresponding to the inclination of the complemental bevels 27. 1 This flange carries adjusting screws 29, co-acting with thebevels 27. Incidentally the'screws'are provided withjam nuts; It is obvious that this arrangement permits adjusting of the bushing to compensate for wear and to allow for irregularitiesI and to conform to the surface of the shaft against which it'is bound. The bevelled surfaces of the bushing 22 and the complemental bevelled surface and flange of the annulus23, together with the cooperating contacting the resilient portion or sect I durance and proper adjustment.

screws, produces a desirable cam action for against the shaft. 7

In practice, anti-friction balls or equivalent elements 30' are interposed between the inner and outer races 28 and 21, respectively, and are preferably confined in annular grooves or race ways. j v

A bearing of this type is e remely practical to use in transmissionmachinery, al-

though it is equally well adapted to other uses. It is obvious that this construction pro vides simplicity and economical manufacture, quick assembly, subsequent repair,'and en- Itis thought however, that these advantages and others will be quiteapparent after carefully considering the description in conjunction with the drawings. 7 Therefore a more lengthy descriptionis regarded as unnecessary. Minor changes in shape, size, and rear rangement of details coming within the field ofinvention claimed maybe resorted-to, in

actual practice, if desired. 9 Iclaim: r I a 'l' .1.
